8994 Can't run existing VM on new Sandy Bridge computer. sebudge "I just upgraded my computer to a i5-2500k (Sandy Bridge) processor in an MSI P67A-G45 motherboard. I experienced two different problems. First, the 32-bit WinXP VM I was running previously without problems will hang after it boots when it reaches the login screen. Second, when I tried to install a Windows 7 VM (64-bit) I get a message that ""VT-x/AMD-V hardware has been enabled, but is not operational."" The 64-bit Windows 7 will not install, even though VT-x is set in the BIOS on the motherboard." defect closed critical installer VirtualBox 4.0.8 invalid VT-x, Sandy Bridge Windows Solaris
